When weather conditions are ideal, some ferns, algae, moss and even fungi, release spores into the air, often carried by the wind, by insects or birds until they land. Spores contain both male and female reproductive organs, which allows these plants to replicate themselves in a form of cloning.
Geothermal Energy and Solar Energy
The correct answer is option (B) lemon juice.
pH refers to the logarithmic scale used to indicate the acidity or basicity of an aqueous solution. It is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less that 7 are considered acidic and the solutions with a pH greater that 7 are considered to be basic. A pH of 7 is neither an acid nor a base and is considered neutral.
An acid has a high concentration of hydrogen ions (H+) and a base has a low concentration of hydrogen ions. Higher the hydrogen ion concentration, pH is acidic. Among the given substances, lemon juice has a pH of 2, urine has a pH of 6, tomato juice has a pH of 4 and black coffee has a pH of 5. Since lemon juice has a pH of 2, it has the lowest –OH ion concentration.

Explanation:
I wont be able to answer your full question due to that I don't know where your home is located.
<h2><u>Question 1</u></h2>
Four possible sources of energy in your home are:
Thermal Energy, like your microwave or oven
Solar Energy, solar panels if you have any
Wind Energy, like a fan blowing
Electrical Energy, like plugging in a device
<h2><u>Question 2</u></h2>
Probably, in our world today, your home would mostly be powered with one of the following:
Solar Energy: If you have solar panels installed. They generate a lot of energy for electricity.
Electrical Energy: Power Plants create electric energy that go through cables to millions of billions of homes. Electrical Energy is most people's main source of power due to electric companies providing it every second.
I will continue on, in order to answer Questions 3 and 4, your location is required.
Hope this helped! :)
